And the manual visual auditing mode has limitation and is easy to make mistakes.

The standard library module is used for storing a plurality of standard templates so as to be used for the core to call the modules. The standard templates in the standard library module cover the circuit schematic diagrams of different combinations of LCD models and IC models as much as possible so as to meet the calling requirements of various circuit schematic diagrams to be audited. The plurality of standard templates are named according to a uniform rule, namely the names need to include the LCD model and the IC model in the templates. And the standard template needs to be converted into EXCEL, WORD, PDF or TXT files and the like through external software (such as EDA and the like); preferably EXCEL files, which are displayed in a list form and are convenient to check and review.

The input module is used for importing a circuit schematic diagram to be checked, the imported circuit schematic diagram is also converted into a file with the same format as the standard template through external software, and the imported file is temporarily stored in the cache area of the checking module. And then inputting key parameters of the schematic diagram of the circuit to be checked into a selection frame of the selection module, wherein the key parameters are the LCD model and the IC model.

3. sequentially checking data under the same PIN number in the cache area, judging that the data under the Standard OLB Project is the same as the data under the Project OLB Project and is judged as True, and judging that the data under the Standard OLB Project and the data under the Project OLB Project are different and are judged as Fail; the data in the Standard TO Project is judged TO be True and the data in the Project TO Project is judged TO be Fail.

Finally, the output module outputs the checking result, wherein the outputting the checking result comprises: a verification file, preferably an Excel file, is output. And displaying the item (namely, the item judged as True) of the circuit schematic diagram to be detected in the check file, which is consistent with the standard template, as a first color, and displaying the item (namely, the item judged as Fail) which is inconsistent with the standard template, as a second color. The first color is generally green and the second color is red, so that the contrast is clear, and the items for judging Fail can be further checked conveniently.

And each standard template is named and stored according to the LCD model and the IC model. The standard template in the standard library file covers circuit schematic diagrams of different combinations of various LCD models and IC models as much as possible so as to meet the calling requirements of various circuit schematic diagrams to be detected. The plurality of standard templates are converted into files in the format of EXCEL, WORD, PDF, TXT, or the like, preferably EXCEL files, by EDA software or other software, and the plurality of standard templates in the EXCEL format are stored in the standard library module.

And 3, utilizing EDA software to manufacture and design a circuit schematic diagram of the LCD bonding PIN circuit according to requirements, converting the circuit schematic diagram into a file with the same format as a standard template by utilizing the EDA software, and importing the converted circuit schematic diagram into the input module.
